Article Summary

The North American Industry Classification System (NAICS) is the standard used by Federal statistical agencies in classifying business establishments for the purpose of collecting, analyzing, and publishing statistical data related to the U.S. business economy. 

NAICS uses a hierarchical structure. A “hierarchy” is the relationship of one item to a particular category.

The organization of NAICS is as follows:

  • Sector: 2-digit code
  • Subsector: 3-digit code
  • Industry Group: 4-digit code
  • NAICS Industry: 5-digit code
  • National Industry: 6-digit code
